64127689 ÷ 615 
Our goal is to divide 64127689 by 615.

Let's proceed to step 1:
615 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 615

Going ahead to step 2:
615 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 64 leaves us with 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 615

Step 3:
615 goes into 641 1 times with a remainder of 26.
The next digit of our result is 1. 
Result so far: 1.0
If we take 615 away from 641, we end up with 26.
Grab the next digit (2) from the dividend, add it to 26, then carry on: 262 / 615

Going ahead to step 4:
615 can be fit into 262 0 times, resulting in a remainder of 262.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtracting 0 from 262 leaves us with 262.
Fetch the next digit (7) from the dividend, attach it to 262 and continue: 2627 / 615

On to step 5:
If we divide 2627 by 615, we get 4 and a remainder of 167.
The next digit of our result is 4. 
Result so far: 104.0
Deduct 2460 from 2627 and we're left with 167.
Bring next digit (6) of the dividend behind the 167 and repeat the process: 1676 / 615

Moving on to step 6:
When dividing 1676 by 615, we get 2 with a remainder of 446.
Write down 2 as next digit of the result. 
Result so far: 1042.0
The remainder is 446 after subtracting 1230 from 1676.
Include the next digit (8) from the dividend after 446, then repeat: 4468 / 615

Step 7:
615 goes into 4468 7 times with a remainder of 163.
Put 7 as the next digit of the answer. 
Result so far: 10427.0
Subtract 4305 from 4468 to get 163.
Fetch the next digit (9) from the dividend, attach it to 163 and continue: 1639 / 615

On to step 8:
When dividing 1639 by 615, we get 2 with a remainder of 409.
Put 2 as the next digit of the answer. 
Result so far: 104272.0
If we take 1230 away from 1639, we end up with 409.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4090, and continue the process.

Step 9:
615 goes into 4090 6 times with a remainder of 400.
Use 6 as the next digit of our solution. 
Result so far: 104272.6
If we take 3690 away from 4090, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 10:
If we divide 4000 by 615, we get 6 and a remainder of 310.
The next digit of our result is 6. 
Result so far: 104272.66
Subtract 3690 from 4000 to get 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

The quotient of the division is 104272.66, and the remainder is 0.31.
